PIANO LAMP Filed May 21, 1929 Patented June 17, 1930 UNITED STATES OSCAR HOLTHER, OF ATTLEBOBO; MASSAGHUSETTS PIANO LAMP Application filed May 21, 1929. Serial No. 364,750.

My invention relates to electric piano lamps adapted to be detachably engaged with the top of the front board or sounding board of a piano for illuminating the music rack and keyboard.

The essential objects of my invention are to securely retain heads in engagement with the body of the hood or reflector and with the lamp socket without the use of solder or auxiliary rings, and to adapt the suspension means for the hood to the piano sounding boards of varying thickness in a more facile manner than was heretofore possible. Further objects will be made apparentto those skilled in the art by an inspection of this specification.

To the above and other ends my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification.

Figure l'is a front elevation of my lamp omitting the socket and bulb,

Figure 2, a section on line 22 of Figure 1, and

Figure 3, a bottom plan view of the lamp including the socket and bulb.

Like reference characters indicate like parts throughout the views.

As herein shown in a thin sheet metal hood reflector 5 includes a semicylindrical resilient body 6, horizontally disposed, with the resultant longitudinal light passage 8 in its bottom portion, at both sides of which the margins of the body are provided with tubular beads 9 extending its entire length. The hood is completed by hollow sheet metal heads 10 comprising tapering body portions 11 and inner end flanges 12. The latter are embraced by the end portions of the hood which partially surround them.

Removably mounted in the ends of the heads at each end of the hood are clamping members 14, each comprising a cross bar 15 and stud 16. The latter are held with a degree of friction in the beads,but with slight exertion are withdrawable therefrom. Each cross bar engages the body portion 11 of the adjacent head at a point outside an annular shoulder 19 located upon the body 26 to the lamp socket 22. The conductor is omitted elsewhere than in Figure 1.

Spaced supporting bracket members 27 are provided. Each of these is formed from a strip of thin metal, and comprises a horizontal arm 28 carrying u on its forward end an attaching lug 29 'Xed by a screw 30 to the back lower portion of the hood. A vertical abutment 31 rises from the rear end of the arm, and from its upper end rearwardly extends a horizontal strip 32 terminating in a depending rear abutment 33. The material of the latter is cut and bent to form an integral upwardly and forwardly inclined tongue 34. The tongue is pliable and yielding. Hence when the to of the piano wall enters the socket formed by the bars 31, 32, 33, the tongue 34 compensates for any difference from normal in the thickness of the wall or board. To avoid scratching the portions 31, 32 and 34 of the bracket are lined with felt pads 36, 37 and 38 respectively.

It is important to note that the cross bars 15 of the members 14 snugly interengage the head 10, since the frictional en-, gagement aflorded by solely clamping the hood upon the heads is sometimes inadequate to prevent escape of the heads without the check afforded by the interengagement of the head and cross bar.

I claim 1. In a piano lamp, a reflector hood comprising a horizontally disposed semicylindrical resilient body having its resultant longitudinal open portion in its bottom, and heads comprising tapering body portions, annular shoulders near the inner ends of the body portions, and flanges upon the inner ends of the body portions of the heads embraced by the ends of the hood, tubular beads upon the margins of the body, and clamping members comprising studs in the beads, and cross bars engaging the heads at points outside the annular shoulders.

2. In a piano lamp, a horizontally disposed refiector hood comprising a resilient semicylindrical body having the resultant longitudinal opening disposed in its bottom, heads in the ends of the body embraced by the body, a lamp socket clamped by one end of the hood, a bulb on the socket, tubular beads upon the free margins of the body, and clamping members comprising studs in the beads, and cross bars engaging the heads.

In testimony whereof I have aflixed my signature.

OSCAR HOLTHER.
